Aspire :: OSGi Bundles for Aspire servers

This section describes the OSGi bundles used in the Aspire middleware.

1 Source repository

2 OBR

The artifact will be available soon through an OBR index mapped on a Maven repository.

3 General Purpose

4 Readers

4.1 Libraries

The bundles for readers package only implementation classes imported by the ALEServer barfile (bundle+war) deployed on the OSGi platform.

4.2 Bundles with HALAdaptor services

The bundles package services that are automatically added and removed to the ALEServer' LRSpec list

4.3 UPnP RFID Readers

5 Sensors

5.1 Data exchanges

Data sent by the sensors to the ALEServer are: Data values must be represented in units defined by the International System of Units (such as the org.osgi.util.measurement.Unit).

Sensors data types are named flavors in the WireAdmin terminology.

Other data types could be

5.2 Sensors properties

Sensors and data properties qualify the Producer services and Event properties used in the Aspire components.
  • application.name
  • value.unit
  • ...
UPnP constants can be used also.

5.3 OSGi WireAdmin based sensors

The sensors are developed according the OSGi WireAdmin specification. The bundles for sensors package Producer services. Those service are automatically wired to the Consumer service of the ALEServer barfile.

5.4 OSGi EventAdmin based sensors

The sensors are developed according the OSGi EventAdmin specification. They send/post events containing measures to the ALEServer' topic org/ow2/aspirerfid/aleserver/sensedata. The Event properties are :

5.5 OSGi MonitorAdmin based sensors

The sensors are developed according the OSGi MonitorAdmin specification.

5.6 OSGi UPnP Base Driver based sensors

The sensors are developed according the OSGi UPnP Base Driver specification.

6 Actuators

6.1 OSGi UPnP Base Driver based actuators

The sensors are developed according the OSGi UPnP Base Driver specification.
